A couple of ideas. Pick and choose what you like here, as these are only some ideas:
1) Since I used to buy cigarettes by the carton and my quit was not based on how many smokes were left, I had a few packs left over when I quit. I kept them around for a while, just so there would be no "Should I break down and go to the store now?" drama. ('Cause we all know how this game works: You go back and forth about going to the store, and should it be the expensive convenience store or should you make a real trip to wherever you get your cheap smokes, etc. Then you go to the store to get the smokes, and the urge has passed, but you figure you should buy them anyway since you are there, and since you bought them, you may as well smoke a few...) I figured I was better off just keeping them around for a while. If I wanted to smoke, they were right there. It was up to me to say yes or no. ...From what I've read, this approach is horrible for some and excellent for others. you will have to decide how your mind works.
2) Create a replacement ritual/reward. Perhaps your reward for a long shift will be a tasty snack from the store instead. (Be careful with this one, because the calories can add up. But I think it's OK to be a bit indulgent with the food at the very beginning of your quit.)
3) I've become aware of the HALT (Hungry, Angry, Lonely, Tired) factors that were triggers for smoking. I would also add "Overwhelmed," which can go with the end of a long day. I've found that I need to give myself permission to decompress without a cigarette. This might just be a 5-10 minute escape from my life's obligations. (I was taking those breaks when I smoked, so why not also take them when I don't?) You could carve out some "me time" after the 14 hour shift. Choose a place that you would like to sit quietly and enjoy. Maybe on your porch, in a nearby park, somewhere on your way home that looks scenic or nice, etc. Sit there and deep breathe for at least as long as it would have taken to smoke.
